Water damage to bottom of book: water stains visible to covers, spine, and endpapers. All pages, however, are undamaged, clean, and tight. Pp. 30 and 31 have a great deal of browning, but these are the only pages browned. Sewn binding board book. Holds together wonderfully and is perfectly readable: flaws, although very evident, are only cosmetic and do not affect the reading of the book. DJ has similar water damage, some chipping at edges, otherwise VG. Vintage numerology text from the 1920s.
